Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 11:10

Tidskriftsartikel (refereegranskat)abstract
- Since bicycles and bike-sharing systems are becoming increasingly important in modern transportation contexts, we suggest in this paper an alternative method to incorporate cycling among the freight transport alternatives within urban areas. We propose pursuing a sustainable initiative of crowdsourced delivery where some of the urban good deliveries may be voluntarily undertaken by users of the free-floating bike-sharing systems while following their prefixed route in exchange for some kind of reward. We believe that a network design model that allows properly allocating the resources of the bike-shared mobility service could improve the potential of crowdshipping, making it a viable support and supplement for the local postal services, and more easily accepted and adopted in urban contexts. An application to a case study has been embodied to show the effectiveness and advantages of our proposal.

A geofencing-based methodology for speed limit regulation and user safety in e-scooter sharing systems
-
Ingår i: Journal of Intelligent Transportation Systems: Technology, Planning, and Operations. - 1547-2450.
-
Tidskriftsartikel (refereegranskat)abstract
- The advent and popularity of shared electric scooters in many urban areas worldwide offer new opportunities and challenges to be addressed by the research community, especially as far as safety and accessibility issues are concerned. This paper proposes a methodology, based on geofencing technology (i.e., virtual geographic boundaries) to define in which urban areas the speed of shared electric scooters should be limited. The methodology also helps to prioritize the areas in which to enforce geofencing interventions. Historical patterns of the sharing system usage, crash databases and context/network-related parameters, together with expert judgment, are the main inputs for a geofencing optimization that provides the recommended clustered areas where the speed-limit geofencing scheme can be planned to assure the greater safety of the system. The methodology has been applied to a real case study, the city of Bari, Italy, to show the potential of the proposal.

An approach to modeling bike-sharing systems based on spatial equity concept
- 2020
-
Ingår i: Transportation Research Procedia. - : Elsevier BV. - 2352-1465. ; , s. 185-192

Tidskriftsartikel (refereegranskat)abstract
- Efficient and sustainable mobility is becoming a need for emerging metropolitan areas, essential to grant their attractiveness, quality of life and economic power. Among the possible strategies to adopt, shared mobility systems have proven to be a valuable alternative to accommodate the mobility needs of citizens ensuring at the same time sustainability and transport flexibility. In particular, this paper focuses on bike-sharing systems. Despite many studies have recognized the importance of planning processes supported by equity principles, only a few have integrated spatial equity concepts in the planning of a bike-sharing system. With this research, we want to propose an original model to determine the number and layout of bike stations, as well as the number of bicycles and racks for each of them. The suggested approach aims at minimizing the costs associated with the system implementation and operation while balancing the level of service for all the users over the territory. A set of illustrative examples and a sensitivity analysis are provided.

An urban bikeway network design model for inclusive and equitable transport policies
- 2019
-
Ingår i: Transportation Research Procedia. - : Elsevier BV. - 2352-1465. ; 37, s. 59-66
-
Tidskriftsartikel (refereegranskat)abstract
- This study suggests an optimization framework to plan and design a network of bike lanes in an urban context, based on equity principles and subject to a given available budget. The novelty of the proposal consists in an objective function that aims at minimizing the existing inequities among different population groups in terms of accessibility/opportunity to the bikeways. The proposed methodology represents a reliable decision support system tool that could help transport authorities/managers to select the priority areas of their future investments related to the cycling infrastructures. To prove the effectiveness and value of the methodology, an application with relevant analysis to a test case study is presented.

Evaluating the Efficiency of Bike-Sharing Stations with Data Envelopment Analysis
- 2021
-
Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 13:2
-
Tidskriftsartikel (refereegranskat)abstract
- This paper focuses on the efficiency evaluation of bike-sharing systems (BSSs) and develops an approach based on data envelopment analysis (DEA) to support the decisions regarding the performance evaluation of BSS stations. The proposed methodology is applied and tested for the Malmöbybike BSS in Malmö, Sweden. This was done by employing spatial analyses and data about the BSS usage trends as well as taking into account transport, land use, and socioeconomic context of the case study. The results of the application demonstrate consistency with the literature and highlight meaningful associations between the station relative efficiency and the urban context. More specifically, the paper provides in-depth knowledge about the preprocessing data, selection of input and output variables, and the underlying analytical approach to be potentially applied to other cases and urban contexts. Overall, the DEA-based methodology presented in this study could assist decision-makers and planners with developing operational strategies for planning and management of BSS stations and networks.

Equità e accessibilità nella pianificazione della mobilità sostenibile
- 2021
-
Ingår i: Territorio. - 1825-8689. ; :99, s. 32-39
-
Tidskriftsartikel (refereegranskat)abstract
- One relevant challenge in the field of sustainable mobility is to plan and operate transport services equitable from a geographical and a social point of view. New forms of mobility can exacerbate pre-existing inequalities in the access to public transport systems by excluding some urban areas such as low-income neighborhoods or outskirts, where residents could benefit most from more supply. The goal of this work is to frame these aspects and discuss them taking into account the most recent studies, highlighting the key aspects worth to being explored by researchers and transport planning professionals.

How the built environment and the railway network can affect the mobility of older people : Analyses of the southern Swedish region of Scania
- 2019
-
Ingår i: Research in Transportation Business and Management. - : Elsevier BV. - 2210-5395 .- 2210-5409. ; 30

Tidskriftsartikel (refereegranskat)abstract
- Global society is rapidly ageing. Research on ageing and mobility suggests that better synergies could exist between older people and the built environment. The age-in-place policy will put increased demands on the transport system as a key facilitator for access. The main goal of this study is to examine the spatial distribution of older adults, assessing if it could be affected by selective characteristics of the surrounding built environment and, if so, to what extent. The study district is the region of Scania in the southern part of Sweden. Register-based longitudinal socio-demographic data such as income, employment and education associated with the outcomes of previous travel surveys conducted in the region are the main data sources to be considered. Correlated with population density patterns and expansion of the railway network, this longitudinal approach is expected to reveal causal inferences. Better knowledge may be gained about the environmental and demographic factors that may potentially lead older people to adapt their mobility choices according to the area in which they reside. Research findings could provide useful policy recommendations both to land use and transport planners, contributing to the development of age-friendly neighborhoods, cities and regions.

Ingår i: Transportation Planning and Technology. - : Informa UK Limited. - 0308-1060 .- 1029-0354.
-
Tidskriftsartikel (refereegranskat)abstract
- The implementation of an appropriate pricing policy in an urbanarea could alleviate both environmental and congestion problemsby encouraging a shift towards more sustainable modes oftransportation. However, any positive net social welfare balancedelivered by the policy can hide unacceptable regressive effects.Therefore, it is crucial to investigate any change in relative levelsof accessibility among different categories of transport networkusers.This study focuses on the application of a cordon-basedcongestion pricing scheme on a multimodal network, whereprivate cars and public transportation coexist, and includes asensitivity analysis by varying the size of the charging area andthe amount of the toll, for a monocentric urban reality. Takinginto account an elastic demand associated with each proposedcharging scenario, the related distributional effects are exploredusing the Theil index, with a quantitative assessment of theinequalities in the accessibility variations across the users of thenetwork.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This international study, part of the JPI Urban Europe project EASIER, aims to unravel the governance complexities of intermodality. Through a series of workshops, the study analyses the governance of door-to-door mobility by mapping organisational roles, responsibilities and relationships in the context of multimodal regional transport networks in four countries: Lund/Malmö (Sweden), Copenhagen (Denmark), Berlin (Germany) and Trøndelag (Norway). It highlights the challenges associated with organising intermodal journeys and provides examples of governance mechanisms in each country that support integration and inter-organisational collaboration. Data was collected through workshops with stakeholders representing organisations involved in public transport governance. The workshops aimed to map organisational roles and responsibilities, identify challenges and highlight examples of good practice. Each workshop was structured around an example of a local journey, designed to raise issues of coordination across modal, spatial and organisational boundaries.The results show that door-to-door mobility presents similar challenges across different national contexts. Many of these challenges stem from the recognition that while facilitating intermodal journeys requires comprehensive and integrated planning across modal and spatial boundaries, the governance of public transport is often constrained by fragmented, multi-level structures and regulatory barriers. In one workshop, the door-to-door journey was described as a puzzle; a puzzle that no one takes responsibility for solving. The findings of this study underline the importance of collaboration to create a cohesive and efficient transport network that enables users to make seamless, intermodal door-to-door journeys. The study highlights the value of establishing partnerships and national funding mechanisms with the explicit aim of supporting collaboration, aligning objectives and unifying regulations across complex and fragmented governance structures.
